Answer:
r = 8
Step-by-step explanation:
59 = 7r + 3
Switch sides:
7r + 3 = 59
Subtract 3 from both sides:
7r = 56
Divide both sides by 7:
r = 8

The area of the composite figure = 10,874.1 sq. m.
The perimeter of the composite figure = 406.9 m
<h3>What is the Area and Perimeter of a Rectangle and Circle?</h3>
Perimeter of a rectangle = 2(length + width)
Area of a rectangle = length × width
Perimeter of a circle = 2πr
Area of a circle = πr²
<h3>
What is Area of the
composite figure?</h3>
The figure is made up of two semicircles (1 full circle) and a rectangle.
Area of the composite figure = area of circle + area of rectangle
= πr² + length × width
r = 36.5 + 1.2 = 37.7 m
length = 85.0 m
width = 2(36.5) + 2(1.2) = 75.4 m
Substitute
Area of the composite figure = π(37.7)² + 85.0 × 75.4 = 10,874.1 sq. m.
<h3>
What is Perimeter of the
Composite Figure?</h3>
Perimeter of the composite figure = perimeter of circle + 2(length of the rectangle)
= 2πr + 2(L)
Plug in the values
= 2π(37.7) + 2(85.0)
Perimeter of the composite figure = 406.9 m
